I am using the android myKeypad application (acutally the Pro version) with my Elk M1EZ8 control and HAI RC1000 thermostats. On the myKeypad thermostat menu the current temperature is displayed at the top, and immediately to the right of the displayed temperature, there is a red up arrow, and a blue down arrow. Pressing these causes the displayed temperature to increase, or decrease, respectively, but does not cause the heat or cool setpoints to change (that is done with the thermometer icons further down on the menu). So what setting is being changed by pressing these arrows?
